return to ViewController after presentViewController

Im trying to return to a specific ViewController in it's current state after going from that ViewController to another using presentViewController.

But when I try to close the other ViewController (with dismissViewController) I get a white screen.

RootViewController *rootViewController 
   = [[UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil]
             instantiateViewControllerWithIdentifier:@"RootViewController"];
    [self presentViewController:rootViewController animated:YES completion:nil];

This isn't an option either because that instantiates a new viewcontroller and I want the old ViewController in its current state.

Do I need to pass the RootViewController as an argument when presenting the other ViewController or is there another option to return to the RootViewController in its current state?

Yes, there is a way to return original screen. I met just like problem but solved it with following code line

[self dismissViewControllerAnimated:YES completion:nil];

one way to address this is to avoid having one view controller responsible for presenting and dismissing the other one.. what you can do is create a controller of controllers (give it a singelton method).. and have that object basically keep a reference to any view controller you are interested in maintaining its state. That way you wouldn't have worry about what's going on behind the scenes when you dismiss or present a view controller.
